Viltolarsen (NS-065/NCNP-01) sodium is a phosphorodiamidate morpholino antisense oligonucleotide. Viltolarsen sodium binds to exon 53 of the dystrophin mRNA precursor and restores the amino acid open-reading frame by skipping exon 53, resulting in the production of a shortened dystrophin protein that contains essential functional portions. Viltolarsen sodium has the potential for Duchenne muscular dystrophy (DMD) research[1][2].
Viltolarsen (NS-065/NCNP-01; 2 days) sodium induces exon 53 skipping in cells from a DMD model with a deletion of exons 45-52 with an EC50 value of 0.63 μM and in cells with a deletion of exons 48-52 with an EC50 value of 2.3 μM[2].
Viltolarsen (10 μM; 3 days) sodium causes the dystrophin protein expression in cells from a DMD model[2].
